Popis: We analyse the d-dimensional BEG model with $$d\ge 2$$ and parameters in the disordered region and at the antiquadrupolar-disordered line. We obtain a subset of these regions for which the odd correlation functions are zero and the even ones decay exponentially fast, at all non-zero temperatures, for a wide class of boundary conditions.
